Abstract

OBJECTIVES

This study examined falls self-efficacy and fear of falling to determine whether self-efficacy acts as a mediator between fear of falling and functional ability.

METHODS

Using the Survey of Activities and Fear of Falling in the Elderly as a fear-of-falling measure and the Activities-Specific Balance Confidence Scale for falls self-efficacy, structural relationships among fear of falling, self-efficacy, functional balance, and physical functioning outcomes were tested with older adults (N = 256, M age = 77.5).

RESULTS

Lower levels of fear of falling were significantly related to higher levels of falls self-efficacy, which was in turn associated with better functional outcomes. Moreover, falls self-efficacy mediated the effects of fear of falling on functional outcomes.

DISCUSSION

Results substantiate the hypothesized mediational role of falls self-efficacy in fear of falling and underscore the need to consider ways of enhancing falls self-efficacy in interventions aimed at reducing falls and fear of falling.

摘要

目的

本研究考察跌倒自我效能感和跌倒恐惧,以确定自我效能感是否在跌倒恐惧与功能能力之间起中介作用。

方法

使用《老年人活动与跌倒恐惧调查问卷》作为跌倒恐惧的测量工具,以及特定活动平衡信心量表来测量跌倒自我效能感,对老年人(N = 256,平均年龄 = 77.5岁)的跌倒恐惧、自我效能感、功能平衡和身体功能结果之间的结构关系进行了测试。

结果

较低水平的跌倒恐惧与较高水平的跌倒自我效能感显著相关,而较高的跌倒自我效能感又与更好的功能结果相关。此外,跌倒自我效能感介导了跌倒恐惧对功能结果的影响。

讨论

结果证实了跌倒自我效能感在跌倒恐惧中所假设的中介作用,并强调在旨在减少跌倒和跌倒恐惧的干预措施中,需要考虑提高跌倒自我效能感的方法。
